@freemo This pretty cool too!
@shibaprasad Except for 2
@kravietz 2 is at the power. You can write that as root on the other side or to the power half too!
@shibaprasad well, power *is* part of equation :)
@kravietz
Well then you can use this notation :P
@shibaprasad That works :)
@shibaprasad So does this
\[1=(9-8)*(7-6)*(5-4)*(3-2)\]
